The PetSafe Happy Ride Quilted Dog Safety Seat secures your pup while protecting your seats from pet hair and scratches. The included tether attaches your dogs harness to the seat belt. The sturdy, rigid frame is easy to assemble and install in the front or back seat. The strong, lightweight plastic panels lock together with no tools required. The special 9-inch high raised seat platform makes this a dog booster seat too. Your dog will enjoy sleeping the miles away on the comfy fleece liner and cushion. When needed, the removeable liner can be cleaned in your washing machine.
